Tiivistelmä: The Hydrological Yearbook 2006–2010 comprises annual treatises on hydrological conditions in Finland as well as tables and diagrams presenting daily or monthly means of hydrological variables during these years. As reference values, the means and extremes of the periods 1961–1990 and 1991–2010 are used. In addition to statistics, some articles about the hydrological observations are included. This publication is the last in the history of Hydrological Yearbooks and it is published only in electronic form. Hydrological reports (at environment.fi www-pages) contain partly similar monthly statistics to those presented in the yearbook. Hydrological records can be browsed and downloaded at www.ymparisto.fi/oiva. Summaries are presented for the following variables: water level, discharge, runoff from small basins, areal precipitation (not corrected for gauge errors), regional water equivalent of snow, evaporation from the Class A pan, temperature of surface water (during the ice-free season), freeze-up and break-up dates of lakes, ice thickness, groundwater level, snow depth and soil frost depth. The tables for each of the hydrological variables are preceded by a description of the methods of observing or computing that variable, as well as notes on the coverage of the monitoring network, and in some cases also a map of stations.
